Black, forming very thin, effused patches. ^ Fertile flocci springing from
creeping filaments, erect, straight, septate, divided above into a few short
furcate or trifid ramuli, which are surmounted by curved 3-7 septate spores,
whose articulations are strongly constricted. A small but neat species, remarkable
for the short-forked ramuli. The tips of these are often greatly
constricted at the articulations when the spores begin to grow.—B. & Br.

The flooci are stiff and erect, and when ripe of a very dark brown, or almost
black colour, being so opaque th at it is a matter of dififlculty to make
out th at they are septate. At tbe apices of the flocci there originate several
rows of almost colourless cells, arranged m a moniliform rnanner, and spreading
in different directions. The spores are attached in rows at the extremities
of the chains of colourless cells, and are of a rich brown, usually
somewhat narrowed at each end, and divided by several transverse lines,
which have the appearance of septa. —Cwrr.
